Christopher Lloyd

Independent Spirit Award for Twenty Bucks (1993), best supporting actor.
Graduate from Staples High School in Westport, Connecticut, in 1958.
His “Taxi” (1978) character, Reverend Jim, was a big fan of the original “Star Trek” (1966). Lloyd later went on to play the Klingon commander Kruge in Star Trek III: The Search for Spock (1984).
As a young actor, he performed at the Yale Repertory Theater with Meryl Streep.
Has appeared in over two hundred plays, including many on Broadway, regional, and summer stock productions.
His second cousin, John Willis, works for the Vermont Food Bank.
For his brief 1985 scenes in Back to the Future (1985), he wore prosthetic make-up to appear 30 years older than in his 1955 scenes, which dominate the film. In the sequels, the 1985 Doc Brown has more scenes. To avoid having to put him through extensive make-up every morning, writers Robert Zemeckis and Bob Gale came up with the idea of Doc Brown visiting a rejuvenation clinic in the future, which results in his face looking much younger.
Attended the Neighborhood Playhouse in New York City.
Attended the prestigious Fessenden School in West Newton, Massachusetts.
In a scene in Back to the Future (1985), his character Dr. Emmett L. “Doc” Brown, hangs on the arm of a large clock. This mimics a stunt done by Harold Lloyd (no relation) in the movie Safety Last! (1923).
To prepare for the role of Taber in One Flew Over the Cuckoo’s Nest (1975), he lived in a mental institution for a few weeks and studied the patients. He modeled his character after one of the patients and stayed in character throughout all filming even when not on screen.Read More on IMDb
